DETAILED DESCRIPTION

Conventionally, there may be various different port assignment enginesat each layer (e.g., separately at Layer 2, Layer 3, or Layer 4) of anetwork. Conventional port assignment engines are limited in scope, inwhich their major role is just to find an available port on a device inthe network. The disclosed subject matter allows for the dynamicassignment of ports for a service path (e.g., connection topology),which may be used to find an optimal path in the network at multiplelayers.

FIG. 1 illustrates an exemplary system 100 for enterprise portassignment. As shown with system 100, there may be customer premiseequipment 101 (CPE 101) which is located at a customer premise. CPE 101may connect to network 111 which may have multiple paths to differentnetwork devices (physical or virtual), such as network devices 102,network devices 103, or network device 104. Further, network device 102,network device 103, or network devices 104 may connect with anyplurality of networks, such as network 105, network 106, or network 107.Network 105, network 106, or network 107 may also have multiple pathsthat may connect with multiple devices, such as network devices 108,network devices 109, network devices 110. Network devices 108, networkdevices 109, network devices 110 may connect with network 112 and so onand so forth. Each connection may require a physical or virtual portassignment associated with different layers for a service. Server 115may be communicatively connected with each device or network of system100. Server 115 may be used to determine and automatically assign orselect the appropriate service path, which may include multiple networkdevices and physical or virtual ports.

Table 1 defines abbreviations or acronyms. Table 2 provides examples ofuse cases for enterprise port assignment (EPA). In an example, there mayan SDN-A application that has multiple services, such as P1, P2,NCX-Hub, or DCU. The disclosed system may analyze the application, theselected service, and prepare the service path, which may includeassigning and selecting the optimal port for the service path atmultiple layers (e.g., open systems interconnection layers). Withreference to FIG. 1 , the ports may be virtual or physical ports, thatmay include port 121-port 124, based on different factors, as disclosedin more detail herein. As shown in FIG. 2 , there is Canopi and LPP,which are different application. They manage separate sets of networkequipment, CANOPI manages L2 IPAG network, LPP manages L3 access andbackbone routers. Some services, like AVPN, ADI, ASE use both sets ofequipment and, conventionally, equipment (port) selection is doneseparately in both applications. In fact, in CANOPI it is done manually.As disclosed, with EPA, the network equipment is managed in the sameplace in terms of homing and capacity and optimization of the network.This may give network providers perspective regarding where and how toinvest and expand the network on one hand, and add automation to theprovisioning processes, both for infrastructure and for customerservices.

With continued reference to Table 2, the table shows the PA functionconventionally in place in these applications. Although not exactly thesame, all these functions are related to selection of network equipment(port, VNF) and allocating network capacity. Conventionally thesefunctions have different level of automation in different applications.EPA automates this process end to end and at the same time manages thenetwork capacity. EPA provides for automatically finding an optimum pathfor a service in the network (e.g., it selects and assign the ports inthe path). In the VNF case, since VNFs are dynamically created (ondemand), EPA also needs to determine where the VNF is created (e.g., VNFhoming) and then assign the VNF (e.g., port on VNF). In addition, pathselection may also be based on available capacity, such as bandwidth,number of connections on the same port, etc. Since some IDs are selectedfrom a range, potentially they limit the capacity as well, so assigningthose IDs, like VLAN ID, may be part of the selection and assignmentprocess. Example functions, as shown in Table 2, are currently performedby separate applications, implemented in different ways, with variousdegree of automation. Based on the disclosed EPA that includes end toend assignment automation, the functions in Table 2 may be necessarilyperformed during that end-to-end assignment.

FIG. 3 illustrates an exemplary method for enterprise port assignment.At step 141, server 115 may receive equipment inventory information. Theequipment inventory information may include information regarding theequipment for multiple connection topologies (e.g., service paths). Asshown in FIG. 1 , there may be many different devices and paths in anetwork that may be used to place a service in operation. Server 115 mayobtain the equipment inventory information of the different equipment.The equipment inventory information may include information about thevendor of the equipment, the model of the equipment, the operatingsystem version of the equipment, the type of the equipment (e.g.,router, switch, fiber module, etc.), or function of the equipment (e.g.,route reflector or optical network terminal).

With continued reference to FIG. 3 , at step 142, an indication of aselection of service endpoints may be received. For example, there maybe an indication to implement the service from CPE 101 to network 112.In another example, the endpoints may be inferred by the type of serviceor other information. At step 143, a parameter of a service may bereceived. The parameter for the service may include a type of theservice, location of the service, minimum upload speed of the service,minimum download speed of the service, quality of service profile of theservice, latency requirement of the service, type of connectionpreferred or required by the service, or service level agreementrequirement of the service, among other things. The type of the service(e.g., see Table 2) may include Internet access, virtual private network(VPN), software-defined networking in a wide area network (SD-WAN),Internet protocol television (IPTV), voice over Internet protocol(VoIP), or Ethernet virtual circuit (EVC), among others.

At step 144, a connection topology may be determined based on theinformation of step 141-step 143, such as equipment inventoryinformation, a parameter of the service, or the service endpoints. Inanother example, the connection topology may be determined based oninformation such as homing rules, which may include a homing constraint,a homing preference, or a homing capacity rule. In an example, thehoming preference includes a preference to choose the closest equipmentto a location of the service or port with least available bandwidth. Inan example, the homing capacity rule includes a maximum port bandwidthfor the service, maximum number of virtual services, or maximum numberof subinterfaces (e.g., logical subdivision of physical or virtualinterfaces). The connection topology may be determined based on aconsideration of one or more thresholds (e.g., homing capacity rule,number of virtual services, bandwidth, etc.), which may assist inoptimizing the use of a service or the network facilities. In a firstexample, there may be a homing rule for a particular service thatrequires ports of the service to have maximum average bandwidththreshold (e.g., exclude ports with less than 1 gigabyte and have anaverage percentage of use of 60%). In a second example, there may be ahoming rule that requires a threshold type or amount of hardware orsoftware resources. The hardware or software resources may include avirtual computer processing unit (vCPU), a network interface card (NIC),or computer memory. The homing rule may help balance traffic or requirethe consideration of particular network equipment or port until itreaches a threshold resource usage (e.g., 60% memory or 70% bandwidthusage).

With continued reference to FIG. 3 , at step 145, an alert may beautomatically sent based on the determining of step 144. The alert mayinclude a description of the connection topology for the service (e.g.,a map or text description) or other information. The other informationmay include the connection topology for the same or different servicesalong the same or similar service path (e.g., two or more identicalports for the connection topology). The connection topology may includea plurality of port assignments for each equipment or network. Inanother example, the alert of step 145 may include instructions to theequipment of system 100 to assign or implement the port assignmentsaccording to the connection topology.

The disclosed EPA system can manage network capacity. The EPA maydetermine ports for multiple layers while preparing a connectiontopology (e.g., a service path), such as layers 1, 2, 3, or 4 withregard to physical or virtual network devices. The service path may beoptimized after evaluating several factors, such as endpoints for aselected service, connection type, service parameters, equipmentinventory information, network inventory information, equipment specificrules, service or connection specific rules, or resource informationassociated with the equipment or network, among other things. Thedisclosed EPA system may also help optimize a service based on distance(e.g., minimize provisioning connection length), latency (e.g., minimallatency), or licensing. Licensing is an example of parameters orrestrictions that we may have during homing, e.g., based on licensingcost, we may decide to reuse a VNF, or where to create a new one. TheEPA system may use machine learning to automate network capacityplanning and management and provide information that may be used forpredictive analysis in a network. For example, the EPA system mayproduce reports on used and available capacity and utilization trendsand may proactively and dynamically adjust homing rules (e.g., based onutilization patterns of one or more layers).
